Inter-linkages among various components of dairy based farming systems in Mizoram State

Abstract

Farming system approach has been widely recognized and advocated as one of the tools for harmonious use of inputs and their compounded response to make the production system sustainable. The present study was conducted to examine linkages among various components of farming systems in Mizoram state by using Leontief input-output model. The study identified 10 dairy based farming systems based on the major contribution to income of farm enterprise. The inter-component linkages from livestock to crop were stronger as compared to crop to livestock for all the farming systems. The degree of integration of different components of the various farming systems in terms of linkages is found to be strongest under D + C + P + Po farming systems. The interdependence observed among various components of farming system suggests the need to adopt total systems approach for development of sustainable farming systems.

Optimizing Farm Plan in Saline and Normal Areas of West Bengal - A Lexicographic Goal Programming Approach

“…The farming systems identified in saline and normal areas of the study area in West Bengal are presented in Table 1. Lalrinsangpuii, 2017).The comprehensive farm planning model for livestock-based farming systems with the goal achievement function vector, the absolute constraints, the goal constraints and the non-negative and zero constraints is given as follows:…”

“…The resource constraints such as land, labour, capital and forage availability were the major resources used in the current study. Similar resource constraints were used in the earlier studies of Saha (2003), Rohaeni et al (2014), Lalrinsangpuii (2017) and Kumari (2020). There were three objectives to be achieved in this study, namely; 1.…”

“…The priority was estimated based on farmers' preferences among three goals under each farming system. Garett's ranking technique was used to prioritize the goals (Kumari, 2020;Lalrinsangpuii, 2017). The comprehensive farm planning model for livestockbased farming systems with the goal achievement function vector, the absolute constraints, the goal constraints and the non-negative and zero constraints is given as follows:…”

“…Optimum farm plans were developed using the lexicographic goal programming technique. The lexicographic goal programming model will achieve goals according to their priority (Kumari, 2020;Lalrinsangpuii, 2017). Goal with the highest priority will be achieved at first and then subsequent goals.…”

“…Hence, farmers should divert available resources to livestock enterprises. Lalrinsangpuii (2017) used the goal programming technique to obtain an optimum plan for the dairybased farming system in Mizoram state. Four goals were considered such as G 1 (to increase farmer's profit), G 2 (to increase the utilization of faeces as fertilizers, G 3 (to increase the utilization of agricultural waste as fodder and G 4 (to increase the absorption of agricultural labour).…”
